Abstract

The adhesion-strength test jig for bonded soles on shoes determines the bond strength over the entire length of the sole. The tip of the sole is gripped by a claw which is suspended from the operating lever of an indicating instrument registering the force exerted. The shoe is held in a last below the claw which moves vertically on upright guide rails. The last is driven downwards by a motorised feed screw or similar mechanical arrangement to exert a tearing force between the shoe and the sole. To ensure that the applied force is always perpendicular to the last, the last is carried on a sliding plate so that it moves progressively up an incline towards the front of the mounting.

Description

Prüfgerät für Schuhsohlenhaftung Tester for shoe sole adhesion

Die Erfindung betrifft ein Prüfgerät das die Haftung der aufgeklebten Schuhsohle am fertigen Schuh misst.The invention relates to a testing device that checks the adhesion of the glued on Measures the sole of the shoe on the finished shoe.

Durch die vielfältigen Materialien für Schuhobermaterial und Sohlen kann eine einwandfreie Verklebung der Materialien nur noch im Versuch ermittelt werden, wozu z.Z. noch keine spezielle Priiffgeräte im Handel sind. Bei dieser Prüfung ist es für eine genaue ermittlung der Haftfestigkeit über die gesammte Länge der Schuhsohle wichtig, dass die Abreisslinie der Sohle mög= lichst senkrecht unter der Messeinrichtung ist. Diese Aufgabe wird dadurch gelösst, dass der Schuh, nachdem die abnehmbare Kralle (Fig. 1 I) an der Spitze der Sohle befestigt wurde, über den Aufnahmeleisten gezogen wird und die Kralle an der Öse, die mit der Zugdose verbunden ist, eingehängt wird.Thanks to the wide range of materials used for shoe uppers and soles perfect bonding of the materials can only be determined by trial become, why currently There are no special test devices on the market yet. In this exam It is used for an exact determination of the adhesive strength over the entire length of the It is important for the shoe sole that the tear line of the sole is as vertical as possible the measuring device is. This task is solved in that the shoe after the removable claw (Fig. 1 I) was attached to the tip of the sole over the The mounting rails are pulled and the claw is attached to the eyelet, which is connected to the pulling box is attached.

Dadurch, dass der Aufnahmeleisten fest auf einem Schlitten, der sich axial, nach vorne steigend, verschieben lässt, montiert ist, schiebt sich der Schlitten entsprechend der abgezogenen Sohle nach vorne, so dass der Abreisswinkel immer bei ca. 90° ist. Der Schlitten mit der Parallel führung ist fest auf eine Halterung montiert die sich während des Prüfvorganges nach unten bewegt.This means that the mounting rails are firmly on a slide that is axially, rising forward, can be moved, is mounted, the slide moves forward according to the removed sole, so that the tear-off angle is always at is approx. 90 °. The slide with the parallel guide is firmly on a bracket mounted which moves down during the test process.

Zwei Ausführungsbeispiele sind in der Zeichnung dargestellt.Two exemplary embodiments are shown in the drawing.

Der Schlitten ist auf Rollenlager geführt um eine leichte Gangart zu erzielen.-æs show: Fig. 1 and Fig. 2 complete device schematically drawn Fig. 3, Fig. 4, Fig. 5 parallel guidance of the receiving strips (11) with an incline upwards directed leadership. The slide is guided on roller bearings at an easy pace to achieve.
